Automatic C & Z Purlin Roll Forming Machine - 20 Forming Stations

Automatic C & Z Purlin Machine Overview

Structural purlins need straight, twist-free sections because every bend error multiplies across a roof bay. This Automatic C & Z Purlin forms the target purlin sections with driven stations sized to the material thickness you run, then straightens and cuts to length automatically, so the purlins you supply go up on site without forcing or re-drilling.

Typical Applications of the Automatic C & Z Purlin

Heavy-duty versions run thicker coil for main structural members, while lighter sections feed secondary framing. We help you match the forming station count and punching options to the section range you plan to sell, so you do not pay for capacity you will not use in the first two years.

Key Specifications of the Automatic C & Z Purlin

Forming stations: 20
Section types: C and Z purlins (two-in-one, one line runs both)
Section range: 80 mm to 350 mm web depth
Material thickness: 1.5-3.0 mm standard; 4-6 mm on heavy-duty versions
Cut length accuracy: approximately plus or minus 1 mm
Punching: optional hydraulic or servo unit, synchronized with the PLC
Control: PLC with stored programs for repeat sections

Key Features

One line runs both C and Z sections by changing the roller arrangement and program, usually cheaper than two separate machines
Optional synchronized punching for end plates, bracing holes and slots, with hole positions locked to the cut
Encoder-synchronized cutting holds finished lengths to roughly plus or minus 1 mm, with continuous PLC counting on long runs
Solar mounting and strut sections supported, including 41x21 strut channel and heavier rails
Forming station count and punching options matched to the section range you plan to sell, so you do not buy capacity you will not use
OEM/ODM build to your section drawings, with a full production test before shipment

Customization, Testing and After-Sales Support

Programmable punching is available as an option: bolt holes for end plates and bracing are punched during forming, so your customer assembles the frame faster on site and you can charge a premium for a ready-to-erect product instead of raw lengths.

Frequently Asked Questions

Can it punch holes automatically?

Yes. The optional hydraulic or servo punching unit is synchronized with the PLC and can be programmed for end plates, bracing holes or slots. Hole positions stay aligned with the cut because both use the same program.

What thickness range is supported?

Standard purlin lines typically run 1.5-3.0 mm; heavy-duty versions extend to 4-6 mm depending on the model. The frame, gearbox and cutting unit are sized to the thickness you plan to run, so confirm your maximum gauge when requesting a quotation.

Do you supply lines for solar mounting profiles?

Yes, we build purlin and strut lines for solar mounting frames, including strut channel sections such as 41x21 and heavier rails. Specify the section drawing and coating and we will confirm the configuration.

Does it run both C and Z sections?

The two-in-one design runs C and Z profiles on one line by changing the roller arrangement and program. If you need both sections, this configuration usually costs less than two separate machines.

What section sizes can this machine form?

The machine is tooled for your section range, typically C and Z purlins from 80 mm to 350 mm web depth; heavy-duty versions handle thicker material up to 6 mm. Send your section drawings or size list and we confirm the forming stations and tooling.

How accurate is the cut length?

The cutting system is synchronized with the line encoder, and finished lengths are held to approximately plus or minus 1 mm. Longer programs run continuously with the PLC tracking the count.

What is the minimum order quantity?

The MOQ is 1 set.

What material does this machine process?

It processes PPGI PPGL GI GL coil.

What is the warranty period?

A 2 years warranty applies, with machinery test report and video outgoing-inspection provided.

Can the machine be customized for my profile?

Yes. Roller sets and profiles can be customized to your drawings, and OEM/ODM service is available.
